SOC correction method adopting voltage dynamic compensation optimization

The invention discloses an SOC correction method adopting voltage dynamic compensation optimization, and relates to the technical field of lithium batteries, and the method comprises the steps: determining a dynamic terminal voltage based on a real-time temperature, a minimum monomer voltage of a power battery pack and a working current flowing through the power battery pack; the SOC value corresponding to the point with the OCV value being the voltage value of the dynamic terminal voltage in the SOC-OCV curve of the power battery pack is determined as an SOC target value, an SOC initial value obtained through calculation according to a preset SOC algorithm is corrected into the SOC target value according to a corresponding strategy, and the SOC value dynamically follows the data curve of the voltage, so that when the under-voltage protection is triggered, the voltage value of the dynamic terminal voltage is not influenced. And the corrected SOC target value is reduced to 0, so that potential safety hazards c
